Each inductance tap is soldered to decade switch contacts, forming a 0-10 variable step adjustment circuit. The product features red and black color-coded terminals for easy identification of same-phase connections. It is recommended to avoid placement near ferromagnetic materials during use to prevent measurement inaccuracies.2213
Applications
The FMT20 Decade Inductance Box is primarily used in university electrical and electronic laboratory teaching, suitable for experiments such as first-order and second-order circuit responses, power factor improvement, and AC parameter measurements. It also serves electronic engineers in debugging filter circuits and resonant circuits during research and development. Each step panel can be used independently or connected in series to expand the adjustment range, offering flexible usage options.210
